I have two usb hdds connected to a usb hub. I've never had any issue with it(the hub). After I installed the last update 10.7.3 everytime I restart my computer if I have the hub (with all my hdds and other devices) connected to my computer, the computer won't boot. It get up to the white screen (before the loading wheel). If I unplug the usb cable it starts booting inmediately.

I have a black macbook. My computer wouldn't turn on, so I plugged it in and turned it on. I noticed that it said "Not Charging". I figured it would go away and start charging. I closed the computer and came back an hour later, and the light on the charger was still green and not amber. Why will my computer only turn on when plugged directly in, and why won't my battery charge? Do I need to get a new charger or a new battery.
View 2 Replies View RelatedI think the title pretty much explains it all. I'm wondering if there's any harm that would come from leaving the power adapter plugged in all the time, but without the MacBook connected some of the time. I'm a college student, and with the way I have my desk set up, I can't really take the power adapter with me everywhere I go. So yeah, I was wondering if there was any harm that would come from it.

I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.
I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.

I have a G3 iBook I've put together from spares just as a project. Everything works fine and will connect to the internet over the ethernet cable.As soon as I plug an Airport card in it refuses to boot, it won't even try so it seems to be a hardware issue.Is it possibly a dodgy Airport card or something else?It's a 2001, 600Mhz, Dual USB, white 12" iBook.
View 2 Replies View RelatedI have a mid-2010 MBP. Earlier when I was not actively using it, it started beeping very loudly in evenly spaced intervals every few seconds. It seemed unresponsive, so I turned it off by holding the power button. Now it will not boot up. The little white indicator light comes on and I can hear the fans turn on, but that is it. It will not even go to the boot screen.
I had the logic board replaced about a week ago, but otherwise nothing new has been installed software or hardware.
I was copying over a SD card via the SD Card read to my internal hard drive. Half way through it froze. And it wouldn't let me do anything. I removed the memory card and all I or was a spinning rainbow circle. So I powered off the MacBook manually (holding power button). When it started up again it came to the apple logo. And froze. So like a idiot I manually powered off the MacBook again. Next time it booted it showed me the stop sign.I tried to boot from cd (holding C while laptop starts), the disk spins but ends up hanging on a White screen. Now I don't mind reinstalling OS x over it. But I just need one folder from It. Is there anyway I can connect this MacBook to my mac pro browse the MacBook internal hard drive and copy over the folder I need?

View 2 Replies View RelatedI have a friend who's oldish-Unibody MacBook Pro started giving him the folder with question mark-flashing symbol on boot-up. I guess it could be PRAM, but in any case, he wants to get his data off the hard drive. The computer wouldn't boot up from the install disk (holding 'c' on boot), all I have managed is to put it into Target Disk Mode, with my own MPB. The funny thing is, that it works, but all that mounts on my computer is the Install Disc (in his disk drive) and his hard drive shows up in my disk utility (see below), but it will not mount, and if I try to repair it, it gives me an error and DUPLICATES the original 'root' drive. Does this mean the hard drive itself is damaged and we need to go to a 'data specialist' to get everything off or is there anything else I could try?
View 2 Replies View RelatedI have an older iMac, 20-inch late 2006. Model Identifier iMac5,1. Processor 2.16 GHz Core 2 Duo, 3 GB RAM. Running OS X Lion 10.7.4. Suddenly the computer has started to behave erratically. It has been crashing and will no longer boot properly. It will boot OK in Safe Mode, but I can no longer make it boot regularly. What can I do to make this work again. When I try to boot normally, I cannot get past an all white screen, after I hear the start up chime and see the Apple logo. I do have a feeling that OS X Lion is just too much for this computer, and I do plan to buy a new one very soon. Hopefully new iMacs will be announced tomorrow. In the mean time I do need to make this work, until I will get a new computer as soon as the new ones come out.

I inherited a PowerBook G4, 10.3.9, from the previous person in this job. I set up my own user account and log-in. Then foolishly I decided to rename the little house icon folder from the previous owner's name to mine. Now when I use my log-in a clean desktop comes up. In the user's folder is the house icon folder with the previous owner's name, and a folder with my name. All my documents are in that folder, so I haven't lost anything. But how do I get computer to boot back into my account?

I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....

I get a message saying "You must restart your computer." (hold down the power key, blah blah).
I've researched a little bit, and apparently its indicative of a kernel panic.
It's not booting from CD either.... what's going on?
